FXstreet.com (Barcelona) - Retail sales volume has increased unexpectedly in December, as a consequence of the special trading conditions of Christmas and the cut on the Value Added Tax, according to figures released by National Statistics.

In December, retail sales have increased 1.6% month on month, following a 0.3% increase in November. Year on year, sales have posted a 4.0% increase, after a 1.3% rise in the previous month, revised down from the 1.5% rise previously estimated.

These figures have beaten the experts' expectations of a 0.6% monthly slump, and a 1.6% year on year increase, although National Statistics warns about the special trading conditions of the Christmas month, which could well have distorted sales figures; these are, firstly, the VAT change, adopted before Christmas sales and vigorous price discounts, and secondly the long lasting sales period this year, ending on the 3rd of January.
